Karl Hilding Lundqvst, Stockholm, Sweden, as-

signory to Kooperativa Frbundet Frening U. P. A., Stockholm, Sweden Application November 7, 1939, Serial No. 303,212 In Sweden November '7, 1938 z, claims. (c1. 19t-so) Vending machines are known for receiving coins and delivering tickets, articles or the like and alsocoins correspondingto a balance, if any. A vending machine of this type for delivering tickets is shown andv described in detail in the British Patent No. 440,763. In the known machines, the change delivering means cooperate with or are controlledby rotatable cam-discs (delivery discs) secured to acommon delivery shaft. The rotation o the delivery shaftV is controlled by a summator, which is adapted torota-te through an angleF proportional to the total value of the coins' entered into the machine and which may preferablyl be constructed" according to the principle disclosed in the U. S; Patent No. 2,173,264. Such machines, however, for reasons given in detailhereinafter, have, heretoforabeen incapable of computing change amountsv exceeding relatively small values. The object of` the present invention is to produce amachine of` this type which is adapted togive change upto relatively large amounts andwhich is simple in construction and operation. l

'The invention willbe described more indetail hereinafter referenceA being had tothe accompanying drawings. In the drawings, however,

such devices and members have been omitted asv are not necessary for understanding the: invention or operate entirely independent ofV the delivery f discs, which are theI essential object of thepresent invention. Thus there have beenomitted suchdevices as the ticket ejector means, means behind the coinslots for testing the genuineness of the coins, a suitable starting and drive device, means for releasing coins, the value or sum of which has notbeen sufficientlyhigh,A i, e, has been lowerthan the price for which the` machine is adjusted. All such devices` are entirely outside ofA the scopeof` the; present invention' and maybe designediin any known manner.

The summator illustrated on the drawings is constructed according to the principle disclosed in the U. S. Patent No. 2,173,264, the design of the members of the summator, however, and its mode of operation, in the present enfibodiment,` differing somewhat from those of the patent. As shown, a number of sleeve shaped elements l are mounted on a shaft 4 rotatable in a frame 3. All the elements l are rotatable about shaft 4 with the exception of the last coupling element l on the right hand side of the machinewhich is fixed to the frame by means of a pin 2. Discs |64, having each a hub portion 2 I, are axially displaceably and rotatably carried on the shaft 4 alternately with the sleeve elements l. Into suit- J- able bores provided in the hub portion 2l of the rst disc |04 on the left hand side of the machine, there project in axial direction pins Z, which are fixed in a hub portion I9 of a toothed disc lli. Similar pins 23 couple the first element I on the left hand side of the machine to the hub portion 2| of the next following disc 164 and so on. Each disc ldd corresponds to one coin denomination and carries on its periphery a single tooth or several uniformly spaced teeth. The number of teeth on each disc lilllis chosen in proportion to the corresponding coin denomination, the disc |04 corresponding to the highest denomination being provided with a single tooth. If the highest denominationis 200 and the lowest denomination is5, the disc liili corresponding to the lowest denomination will thus have 40 teeth. The disc |04 corresponding to the value 10, said disc having consequently 20 teeth, is shown in Figures 11 and 12. The embodiment of the apparatus now described is adapted for Swedish currency. The mechanism is likewise adaptable for other monetary systems after slight alterations apparent to those skilled in the art.

Impulse members 6 actuatable by coins entered in the machine are capable of imparting a reciprocating motion to the discs I 04, as will be described in more detail later on in connection with Figs. 16 and 17. By this reciprocation, the discs |04 are released for rotation and turned substantially in the manner disclosed in detail in the U. S. Patent No. 2,173,264. In the present case, however, the locking member for each disc |04 comprises two teeth III, |02 which are axially and angularly oifset with respect to one another and fixed to or formed from an arm |03 projecting radially from the adjacent sleeve member I, see Figures 1l and 12. The spring force acting on the discs I 04 is obtained by means of a helical spring wound around a shaft 8, one end of said spring being at |05 xed to said shaft 8 rotatably mounted in the frame 3 (see Fig. 1), the other end of the spring at 9 (Figure 2) being united with a toothed wheel II rotatable on the shaft 8. The spring tension is obtained by means of an arrangement described hereinafter more in detail.

The toothed wheel II meshes with a larger toothed wheel I3 on the shaft I2 (Figure 2), said wheel I3 in its turn meshing with a smaller toothed wheel I4 rotatable on the shaft 4. With the toothed wheel I4 is rigidly united a larger toothed wheel I5, in the present embodiment provided with two pins I6, said pins, lowest denomination in this case being ve and the highest denomination two hundred, being adapted to be inserted into two of forty apertures I8 in the disc I'I (Figures 13, 14), which latter, together with its hub I9 is rotatably and axially displaceably mounted on the shaft 4. When the pins I6 project into the apertures I8 in the manner shown in Figures 1 and 14, the spring 'I through the medium of the toothed wheels II, I3, I4 and I5 will strive to rotate the disc I'| in the direction indicated by an arrow in Fig. 2. However, the pins couple the hub I9 of disc I'I and the sleeve members I (except the last one on the righthand end of the machine) constantly to the hubs 2| of the next succeeding discs |04, respectively (counted from left to right in Fig. 1), and as long, as no coin is inserted, each sleeve element is locked to the preceding disc |04 by tooth I0| on arm |03 engaging a tooth of said preceding disc |04. Since the last member at the right-hand end of the machine is held against rotation by means of the pin 2, the spring 'I is prevented from rotating the disc I'I, as long as no coin is inserted into the machine. When, however, one or several coins are inserted into the machine, the impulse members 6, by axially reciprocating the corresponding discs |04, will free each reciprocated disc for a predetermined rotation. Upon movement in one axial direction, each disc |04, corresponding to an inserted coin, is released from the arresting tooth I 0I, whereby the released disc |05, all the members and hubs 2| between said disc and the spring driven disc I1 and said disc I I itself are permitted to rotate until the released tooth on the disc |04 strikes against the tooth |02 on arm |03. When the disc |04 then returns to its original axial posithrough an angle of 9.

tion, it is freed from tooth I 02, and a further rotation of the reciprocated disc |04, intermediate members I and 2| and toothed disc I 'I takes place, until the next tooth on the released disc |04 engages tooth II. If the disc |04, corresponding to a coin value 200, which disc has only a single tooth, is actuated, the disc I'I will be permitted to carry out a full rotation; if the disc |04 corresponding to a coin value 5 and having 40 teeth is actuated, the disc I1 will rotate If both said discs |04 are actuated simultaneously, the total rotation of wheel I1 will be 369. Thus, the total angle of rotation of disc II and wheel I5 coupled thereto will always be proportional to the total value of the coins entered into the machine, as set forth in U. S. Patent No. 2,173,264. The disc I'I has on its periphery teeth with which a spring-actuated detent 'I0 cooperates.

The toothed wheel I5 meshes with a toothed wheell 23 secured to the rotatable main delivery shaft 22 of the machine, and the delivery discs 5, I0, 25, 50 on the said shaft controlling the delivery of certain coin denominations will, therefore, be turned by the spring 'I through an angle corresponding to the entered amount, when the pins I6 are inserted into the apertures I8 in the disc I1. In hitherto known machines all delivery discs have been rigidly secured to one common shaft adjustable in dependence upon the adjustment of the summator shaft. As long, as only small amounts are concerned this arrangement was suicient. However, if the machine shall be used for entering amounts higher than 1 Swedish krona, for instance for prices up to 2 Swedish kronor, the summator shaft and the delivery shaft, respectively, must necessarily be capable of assuming forty various angle positions. Already this complicates the machine to a certain degree, but as soon as the limit of the capacity of the machine must be moved up to, for instance, 4 Swedish kronor, in which case the delivery shaft, the lowest unit being 5 Swedish re, must be capable of assuming eighty various angle positions, the discs 5 will be of too great dimensions to make the machine practically usable, for the discs of the summator as well as of the delivery shaft must, of course, have a considerably greater diameter. With increasing diameter the momentum will also increase, and therefore abutments and the like must be made stronger. Moreover, the machine will also require greater motive power, but in spite thereof the machine will not be able to operate as quickly as a smaller machine with a delivery shaft adapted to assume a smaller number of angle positions.

The present invention, however, solves the problem in a very simple manner as regards construction. According to the invention it is thus possible to use a change giving vending machine, the summator shaft of which must not be able of assuming more than twenty positions at each revolution, although the same may be used for prices from 5 Swedish re up to 18.95 Swedish kronor, In practical use, however, there will be no question of higher amounts than 4 to 5 Swedish kronor. According to the invention the discs 5, I0, 25 and 50 controlling the delivery of the lower coin denominations, as for instance the 5, 10, 25 and 50re pieces, are fast on the shaft 22. In an embodiment of the invention in which the highest coin denomination to be computed at a time is 1 Swedish krona, the shaft 22 is adjustable by the summator to twenty angle positions spaced 18 from one another. The discs 5, I0, 25 and, 50 should, in this case, have the which meshes with a toothed wheel 29 mountedrotatably onone end of a shaft 28being in turn rotatable in a frame portion. 'To the shaft 23 are secured, adjacent the toothed wheel 29, a toothed wheel 3l), of the same shape andy size as the toothedwheel 29, and, on the opposite end ofthe shaft 28, a toothed wheel 3| which is adaptedto cooperatewith a disc 33 having, in the embodiment of the invention illustrated in Figs. 4 to 8, a` single tooth space 32, said disc-33 being fast on the shaft 22 (Figures 9, 10). A coupling wheel 36 carried by an arm 35 rockable about a shaft 34 is adapted tobe brought into and out of driving mesh with the toothed wheels 29, 3B; If the wheel 35 meshes withA thetoothed wheels Zik-3|),

the disc 33, upon each full rotation ofthe shaft 22, will impart a turning movement to the wheel 3|, said movement being transmitted via the wheels 3l), 35 and 29 to the toothed wheel 21-. The disc |50 will thus also assume an angle position corresponding to the entered amount.

In Figs. 4 to 8, thedelivery discs 5, I0, 25, 55 and |03 are shown in their no change positions, which they assume if theA sum of the inserted coins corresponds exactly to the price of the article sold by the machine. It will be understood, that the shaft 22, and, if; the price of the article exceeds 1 krona, also the auxiliary shaft 26, must be adjusted to normal or'restv positions in which the delivery discs are angularly dis,- placed from their no-change positions in the directionopposite to that indicated by the arrows in Figs. 4 to 8 toan extent determined by the price of the article sold by the machine. This adjustment is effected as follows.: While maintaining the driving connection between shafts 22 and 25, shafts 22- and 22v are put out of. driving connection with. the toothed wheel I5 andthe segment gear 51, respectively. The shaft 22 is then turned in counterclockwise direction` (as seenA in Fig. 2) through anangle corresponding to the determined price of the article. termined selling price is 50 Swedish re, theshaft 22 is turned, in: the embodiment shown in Figs. 4 to 8, through anlangleof 180; if the price is l.

Swedishi krona, the shaft 22 is turned through 360 and the auxiliary shaft 26, with the disc: |30.

is turned one step in. counterclockwise direction (as seen in Fig. 2). After the adjustment of shafts 22 and 26, the shafts are again drivingly connected with the toothed wheel l5 and the gear 51, respectively, the cam 45, described in` more detaillater on,` is reset on shaft 22 to theV position shown in Fig. 2, and the machine is ready for operation.

If the selling price of the article is, for. instance, 25` re, the shaft 22 has been adjustedto a position in which the discs 5, I0, 25' and 55 are displaced 90 in counterclockwise direction (asseen in Fig. 2) from their no-change positions.` Assuming, now, that coins to the value of re are inserted into themachine, the-summator will release the delivery shaft 22 for a clockwise rotation through 180", and this sl'xaftwithl the discs 5, lil, 25 and 55 will thus be brought into azposiztion in which 25 re change are delivered, as will be described later on.

In a machine having a delivery shaft and cam single operationis 2.95 kronor.

However, amachine, as shown in Figs. 1 and 2,

provided with al delivery shaft and coin assembly, as illustrated in Figs. 20 to 25, is'capable of; de-

livering change up to 6.95 Swedish kronor in ay single operation.

In this latter embodiment of the invention, the gear wheel 23 is geared to the toothed wheel |51 at the ratio 1` to 1, andthe shaft 22 with the discs.

5, Il), 25fand 5i3is capable of assuming 40 angle positionsspaced 9 from one another in accordance with the 40 angle positions of disc |04. The

forty angle positions are indicated by dot-dash.

lines on the disc 5 in Fig. 20. All the delivery discs, 5, Il), 25, 50, |00 and 250, are shown` in Figs. 20 to 25 in their no-change positions.

The auxiliary shaft 25 carries, fast thereon, in addition to the cam disc |00, the cam disc 200 controlling the two Kronor coin change delivery device. The gear disc 33 is, in this case, provided with two diametrically opposed tooth ,spaces 32 (one of which is hidden in Fig. 2), so that the, auxiliary shaft 26 will be turned one step, eachtime the shaft 22 has completed half a revolution.

The spring 1. is held permanently at' a predetermined tension by means of the device described hereinafter.

On the shaft 8 is fixed a disc 33 having recesses 31. A toothed. wheel 39 isdisposed rotatably and axially displaceably on the shaft B adjacent the disc 38, said wheel 39- being provided with projections Mi corresponding to the recesses 31. In driving mesh with the toothed wheel 39 is a toothed wheel |33, which is driven by a motor not shown on the drawings. An adjustable helicalspring 4| urges the wheel 39 against the disc 3B', and strives to move the projections 45 to engage the recesses 31. l'Ihe projections Il@ will thus serve as drivingmembers for the disc 38. After the projections 4B) have rotated the disc 33 a certain number of revolutions and the spring 1'has received the desired tension, the spring 4| will allow the projections 45 owing tothe resistance of. the spring 1 to leave their engagement with the recesses 31. Immediately after the tension ofY the spring 1 has lowered, the spring having been allowed to rotate the toothed wheel I, the spring 4|. presses once more the projections 43 into engagement with the recesses 31. The tension of the spring 1 is thus held substantially constant.

The discs 5, I5, 25, Ell, |20 and 22E! are restored to. their normal or rest positions at a predetershaft 4; is;held pressed against the cam disc 43,

and, upon rotation of the latter, the end'liTl ofthearmisl displaced to a position in which it is-d-isposed inthe-path of a projection liliv on the cam disc 49 secured to the shaft 22, away fromitsA normal position, shown in full lines in Fig. 2, inv which it permits saidi'disc 42 to rotate in the direction indicated by an arrow in Figurev 2. Against the cam face; |21 of the cam disc 44. (Figure 3), there bears through spring action av pin 53 secured on an arm 52 rockable about apivot 5|.

assembly, as illustrated in Figs. 4 to 10, thehigh` est amountof change-which can be deliveredina` A follower 45, provided:

Upon the rotation of` the cam disc 44 the arm 52 will perform a rocking motion to and fro, and, by a fork member 55 united with the arm 52 and engaging a groove 54 in the hub portion I9 of the disc I1, the latter will be reciprocated on the shaft 4, and the apertures |8 of said disc will consequently engage and disengage the pins I6 on the toothed wheel |5.

Further cam discs 6| and 65 on shaft 42 actuate, during rotation of the latter shaft, Y- shaped arms 63 and 66, respectively, said arms being rockable about a shaft 62. 'I'he arm 63 is connected through a link 64 with the arm 35 carrying the coupling wheel 36, while arm 66 is connected with a link member 59. A gear segment 51 rockable about a shaft 56 and meshing with the toothed wheel 21 carries on a lever arm extending beyond its pivot axis a pin 60 guided in a longitudinal slot 58 of link 59. Elements 6|, 65, 63, 66, 64, 59, 51 and 60 serve to restore the auxiliary delivery shaft 26 to its rest position, as will be described later on.

The mechanism for restoring the main delivery shaft and the auxiliary delivery shaft to their rest positions is claimed in my copending application Ser. No. 327,606.

The abovementioned coupling 335 for restricting the rotation of the shaft 42 to one revolution is substantially constructed as the corresponding coupling in the British Patent No. 440,763 and serves also here the same purpose, but owing to a slight alteration the coupling is described hereinafter with reference to Figures 1 and 19.

A coupling box 338 is xed to the shaft 42. Into said box there extends a bushing or sleeve 336, having fixed thereto a toothed wheel 34|,

which is in driving mesh with the toothed Wheel 39, and a cam member 342. An inwardly projecting tooth 345 on a ring 346 disposed radially displaceably in said box 338 for rotation therewith, is adapted to be engaged by the teeth 343 of said cam member when the ring 346 is shifted to its one radial end position, and to rotate box 338 and shaft 42 in the manner set forth in the British Patent No. 440,763. After a rotation of 360, the projection 348 of the ring 346 through cooperation with the stationary pin 350 shifts the ring 346 back to its inoperative position, thus ensuring that only one full rotation of the shaft 42 is effected.

The coins are entered into the machine via coin chutes |98 (Figures 2, 16 and 17), the number of which in the present case corresponds to the number of discs |64 and the discs 5, I8, 25, 50, and 200 respectively. The coins, in passing the coin chutes |88, cooperate with the corresponding impulse members 6, as will be described hereinafter in connection with Figs. 16 and 17. Each coin chute |88 is connected to a coin receptacle |69. Each coin ejection device comprises an ejecting member adapted to be reciprocated by a gear segment |I0 and an arm I I3 adapted to be rocked upwards and downwards by a cam disc |I2 on shaft 42, said disc being so shaped that the arm I3 retains the plunger ||4 in the position shown in full lines in Figure 15 until the counting process has been nished and the delivery discs 5, I0, 25, 58, |00 and 208 of the machine have assumed their positions corresponding to the entered amount, said plunger I I 4 forming the bottom of the coin receptacle. The counting process having been finished and rotation of shaft 42 having been started, the arm ||3 performs a rocking movement. The pin 5 on the underside of the plunger ||4 is then allowed to-move down and, according to the angle position of the corresponding delivery disc, to bear against the periphery of the corresponding delivery disc or to enter some one of the recesses made in the disc as shown in dot-dashed lines in Figure 15. If the pin ||5 bears against the periphery of the delivery disc, the ejecting member ||I, being displaced and passing through apertures in the wall of the coin receptacle and through a groove ||6 in the plunger ||4, will not strike or take along any coin, but if the pin ||5 enters one of the recesses in the corresponding delivery disc, the front end of the ejecting member strikes and pushes out one or more coins through the slot ||1 in the receptacle, the depth of the recess entered by the pin II5 determining the number of coins ejected. The ejected coin falls through a coin chute |29 to the delivery opening of the machine.

How the segment gears II5) are rocked to and fro will be seen most clearly from Figure 18. This figure shows how the segments are xed to a shaft ||8 visible also in Figure 2. At one end of said shaft I I8 there is xed an arm ||9 which by means of a link member |26 is united with a pin |22 excentrically located on a disc |2I. The rotation of the disc |2| fixed to the shaft 42 will thus rock the shaft |I8 to and fr0, and the segment gears through their cooperation with the teeth |23 of the members will cause the latter to perform a rectilinear reciprocating motion in their guides 24 (Figure 2).

Above each coin receptacle |63 there is inserted in the coin chute |08 a plunger |26 having a central boring |25, Figures 16 and 17. One end of a hook-shaped member |21 xed to the corresponding impulse member 6 bears against the plunger |26 and through the action of a draw spring |28 united with the member 6, which member is rockable about a pin |33, the member |21 strives to press the plunger into the position shown in full lines in Figures 16 and 17. At each coin chute |08 there is also a cross piece |3| interposed. between two displaceable rods |30, said cross piece having fixed thereto a pin |32 of a smaller diameter than the boring |25 of the corresponding plunger |26. Furthermore, there is provided an angle lever |35 rockable around a pin |34, said lever being actuated by a spring |36 (Figure 16). One end of said lever is intended for cooperation with a notch |31 in the member 6 as will be described hereinafter more in detail.

When a coin |38 is inserted in a coin chute |08 the coin will remain in the position shown in Figure 16, the chute portion beneath the plunger 26 being laterally offset relative to the upper chute portion (see Fig. 16). If the rods |30, for instance by depression of an operating member accessible from the outside of the machine, are displaced in the direction indicated by an arrow in Figure 17, the inserted coin will prevent the pin |32 from entering the boring |25 in the plunger |26. The latter will instead be forced against the action of the spring |28 into the position indicated by dot-dashed lines in Figure 16. The member 6 is simultaneously caused to perform a rocking movement, one end of the arm |35 being thereby brought to engage the notch |31 and the corresponding disc |84 is axially displaced by the lower forked portion |39 of the member 6. The coin has simultaneously been brought into register with the offset downward continuation of the coin chute |68. If the rods |38 are now allowed to return to their initial position, the member 6 will for a short time be retained in its displaced position owing to the cooperation between thearm Iand the notchI'Sl. Thereforawlien the pressure of the pin |32Y against' the coin `ceasesr andthe coin is freed to fall down into .the

coin receptacle |59; Immediately before reaching its initial position the cross piece IBI brings the arm |35 out of engagement with the notch |31, the member E' being thereby rocked back to its initial position by the spring |28. Duringthe to4 and fro rocking motion performed by the member 6, the corresponding disc |04 is first released from tooth I|i| and then from tooth |52 of the locking member |53 and is thus allowed to rotatel under the driving force of spring 1 until it has reached an angle position in proportion to the entered coin denomination. The action of the spring 1 is transmitted to the discs |54 through the toothed wheels II, I3, I4 and I5; the pins I5, the toothed wheel I1 and the coupling pins 25 between the hub portion I9 of the wheel |1 and between sleeve elementsv I and hubs 2| of discs |04. The discs |54 in the corresponding coin chutes |08 of which no coin has been entered have not been reciprocated, since 'the corresponding pins |32 have passed into the borings |25 of the plungers |25. Said plungers and the members 6 cooperating therewith have thus remained 'in their positions and the corresponding discs |04 have remained locked by the locking members |03 to the adjacent sleeve members I.

A short summary of the entire counting process will be given hereinafter.

Coins amounting to a Value equal to or more than the price of the article or the ticket arev entered through the coin slots of the machine.

By means of electrical contact devices in the coin a chutes the electrical motor driving the toothed wheel Itis put into function immediately after entering the first coin. During the entering of the coins the toothed wheel 39 and the disc 35 are thus rotated, i. e. the spring 1 is strengthened. When the required number of coins has been entered the rods |35 are displaced in the manner described above, and those discs |54, into the corresponding coin chutes of which coins have been entered, are displaced axially and turned to an angle position relative to the adjacentsleeve member I in proportion to the denomination of the entered coin. The toothed wheel I5, thus, rotates through a total angle proportional to the total value of all coins entered into the machine. Shaft 22 is rotated by gear 23 in mesh with toothed wheel I5, and this rotation of shaft 22 is transferred to the shaft 25 by means of the gearing 33, 3|, 35, 35, 29 and 21 described before in detail. During said transfer the segment gear 51 rockable about a shaft 55 and meshing with the toothed wheel 21 is rocked in the direction indicated by an arrow in Figure 2, and the pin 55 guided in the slot 53 of link member 59 performs a movement corresponding to the movement of the segment gear 51.

After the counting process has been completed another operating member accessible from the outside is depressed, putting the coupling 335 into function via a pin 334. This may, of course, be effected in the manner set forth in the British Patent No. 440,763. This coupling having been put into function, the shaft 42 starts rotating and causes delivery of the article by any known means, as for instance those described in the British Patent 440,763. Simultaneously, arms to the toothed wheel 23 on the shaft 22.

any, haveV been delivered, the arms IIS and the members I |I return to theiry initial positions. The discs 5, III, 25, 5D, |00 and 230 are returned to their rest positions in the following manner. First, during the displacement of members I I I towards the right, the cam disc 43 Vrotating lwith the shaft42 causes the end 41 of the arm 45 to assume the position in the path of projection 48 on cam disc 49 indicated by dot-dashedV lines in Figure 2. Next, cam discs 5I `on the shaft 42 operate the Y-shaped arm 53 and the link member 54 to rock the arm 35 in the direction indicated by the arrow in Fig. 2 thereby causing the coupling wheel 36 to leave its engagement with the toothed wheels 29, 35. Simultaneously, the arm 52, throughl the action of the cam face |01 of cam 44 onthe pin 53, displaces the forked portion 55 andA the disc I1 inY such a way that the pins I5 of the wheel I5 cease toY cooperate with the apertures IS `of the disc- I1 which latter `has been arrested by the summator in the angular position assumed at the end of the counting operation. As a result, the gears I I, I3, I4 and I5 are freed to transmit the turning force of the spring 1 once more At this moment, the shaft 22 is still locked against rotation by the pins II5 being in engagement with the recesses of the corresponding delivery discs, but, when, upon continued rotation of shaft 42, the cam I I2 rocks the arm I I3 to lift the plungers I I4 and pins II5, the shaft 22 is rotated in clockwise direction (as seen in Fig. 2) until the projection 48 of the disc 49 strikes against the end 41 of the arm 46, whereupon the shaft 22 stops with the discs 5, IIJ, 25 and 55 assuming their normal or rest positions. Immediately after the upward displacement of pins II5, the cam discs 65 displace, through the Y-shaped arm 55, the link member 59 in the direction indicated by the arrow in Fig. 2, and, when one end of the slot 58 strikes against the pin 60, the segment gear 51 is rocked in clockwise direction (as seen in Fig. 2). In this manner, the toothed wheel 21 and the shaft 25 with the discs IE5, 250 are restored to their rest positions in a counterclockwise movement.

Towards the end of the rotation of shaft 42 through 360, the cam 44 permits the fork 55 to returns the disc I1 into engagement with the toothed wheel I5, whereupon the arm 46 is forced by the cam disc 43 to reassume its inactive lower position so that the shaft 22 is then retained in its angle position by the engagement between toothed Wheel I5 and disc I1 and no longer by the end 41 of arm 45. Approximately simultaneously with the downward movement of the arm 45, the cam 55 returns the striker member 59 to its right-hand position without causing any movement of segment gear 51. Finally, the coupling wheel 36, having been retained in its angle position by a spring actuated locking roller 51, is returned into engagement with the wheels 25, 35 by the link 54, arm 63 and cam disc 5I.

When the shaft 42 has completed a full rotation, the oblique surface of the projection 343 cooperates with the stationary pin 550 and re- II3 perform their downward rocking movements Y and immediately thereafter the ejecting members I I are displaced towards the right (see Fig. .2). After the article and also the balance, if

turns the ring 345 to its initial position, whereupon the shaft 42 stops turning. Simultaneously, the current to the electrical motor is automatically broken. rihe machine is thus ready for a new operation. Y

Aswill be clear from the foregoing description, the discs 5, I5, 25 and 5I) are rotated in the same (clockwise) direction during the restoring operation and during the counting operation, while the discs |60, 200, during the restoring operation, are rotated in a (counterclockwise) direction opposite to their direction or rotation during the counting operation.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a change giving vending machine having a rotary member, a coin controlled mechanism to rotate said member through an angle proportional to the total value of the inserted coins, a series of change delivery devices adapted to effect the delivery of coins of diierent denominations, respectively, and a series of change delivery discs controlling the different change delivery devices, respectively, the combination of a main delivery shaft, having secured thereto some of said change delivery discs respectively controlling change delivery devices for coins of lower denominations,

Cil

an auxiliary delivery shaft, having xed thereto 20 at least one of said change delivery discs controlling a change delivery device for coins of one higher denomination, means drivingly connecting said rotary member with said main delivery shaft, and gearing between said main and auxiliary delivery shafts, said gearing being adapted upon rotation of said main delivery shaft through a predetermined angle to rotate said auxiliary delivery shaft through a predetermined smaller angle.

2. A machine, as claimed in claim 1, in which said gearing between said main and auxiliary delivery shafts includes an intermittent gear, adapted, Whenever said main delivery shaft has rotated through an angle proportional to the value of the coins the delivery of which is controlled by said delivery disc on said auxiliary delivery shaft, to advance said auxiliary delivery shaft one step.
